I read the other related thread on this common communication failure, but my issue seems to different. When I login through putty to the system, I could not see mysql rpm installed. Running the mysql throws no command found and also checking service mysqld status gives "mysqld: unrecognized service". Did I miss something during instance/stack creation/configuration? Please Help.
Here is the log
